The Master of Death (also known as Conqueror of Death, Vanquisher of Death and others[1]) is the one who masters all three of the legendary Deathly Hallows, which are the Elder Wand, Resurrection Stone, and Cloak of Invisibility. While it is generally assumed that becoming the master of Death refers to some form of immortality, the true Master of Death truly accepts the fact that death is inevitable, and that there are other things worse than dying.[2]

In their youth, both Gellert Grindelwald and Albus Dumbledore had been obsessed with the dream of uniting the Hallows and becoming the Masters of Death. Grindelwald managed to lay claim to the Elder Wand by stealing it from its previous master, Gregorovitch, but never found the other two Hallows. Albus Dumbledore and Harry Potter are the only known people to have held each of the three Hallows, although neither possessed all three simultaneously (the closest was Harry being the Elder Wand's master, though not in physical possession of it, while having both the Stone and the Cloak in his physical possession). Dumbledore regarded Harry as the "true master of death," not because of the fact that he had united the Hallows, but for the reasons he had put them to use.[3]

Known Masters of Death

Ignotus Peverell (only mastered one of the Hallows, but accepted the inevitability of death)

Albus Dumbledore possessed all three Hallows, but not at the same time. He mastered the Elder Wand, borrowed the Cloak of Invisibility from James Potter before giving it to Harry during his first year at Hogwarts, and found the Resurrection Stone in the Gaunt shack. Also he accepted his own death

Harry Potter mastered all three Hallows, but did not possess them all at once (mastering the Elder Wand, owning the Cloak of Invisibility, and having briefly possessed the Resurrection Stone moments before) and accepted his own death
